Yes, that's it, it came off the bolt!
 I removed the tone control assembly again and then I could see exactly what happened!
Thanks so much.
I know I still have my old solder gun in some box somewhere. 
Hopefully that should provide enough heat to attach the braid back to the bolt head!
Looks like I'll have to flip the chassis upside down to make it easier and as I recall that wasn't too hard to do.

I haven't needed or asked for help in ten years and this incredible Philco Phorum comes to the rescue in a couple hours.
Thanks again!
